Bug 2955. Workaround for lack of atomic operations in GCCE standard libraries (fall back to default use of Mutex)
Qt 4.2.1 is a bug-fix release. It maintains both forward and backward
compatibility (source and binary) with Qt 4.2.0.
The Qt version 4.2 series is binary compatible with the 4.1.x and 4.0.x series.
Applications compiled for 4.0 or 4.1 will continue to run with 4.2.
